Draft: Add newest post alert title variable

Using the .Scratch Hugo's functionality, we can store data in our pages. Since the most-recent-box isn't used in a Markdown file, we can't refactor it to be a shortcode and pass the text as a argument. Instead, we need to store data in the Home page and "import" it in our most-recent-box partial .html file.

Closes #10 (closed) .
